fix(gateway): preserve owner isolation when thread metadata is missing (#5484)
* fix(gateway): preserve owner isolation when thread metadata is missing

Follow-up to the #5448 review P1 (post-merge finding): owner_check=True
also authorizes threads whose meta row is missing (legacy compatibility)
or NULL-owner (shared/pre-auth data). _run_scope_user_id returned None
for every trusted internal caller, which dropped the only remaining
per-user filter on those threads and let an internal caller acting for
owner A read owner B's persisted runs.

_run_scope_user_id now takes the thread_id and consults the thread meta
store: when an existing meta row establishes ownership, the authorized
thread's runs are still read unfiltered (merged #5448 semantics,
including owner-header-less internal callers); when the meta row is
missing or NULL-owner, the filter falls back to the acting owner's raw
stamp (the exact value start_run writes) — or the synthetic "default"
identity without an owner header — so cross-user runs stay hidden.

Isolation coverage uses the real MemoryThreadMetaStore with no metadata
row (and a NULL-owner row) plus another user's persisted run: /runs and
/runs/page must be empty and /runs/{run_id} must 404 for internal
callers, while an established-ownership thread keeps the unfiltered
read.

* fix(gateway): gate run-scoped sub-resource reads for internal callers

Review follow-up on #5484: the P1 owner-isolation class remained
reachable through run-scoped sibling reads that apply no per-user filter
at all — /runs/{run_id}/messages, /events, /join, /stream and
/workspace-changes query by (thread_id, run_id) directly, so on
missing/NULL-owner threads an internal caller acting for owner A could
still read owner B's run content by id (verified 200 at the previous
head).

- Extract _thread_ownership_established (shared meta-row check) and add
  _require_run_visible_to_scope: for internal callers on threads without
  established ownership, the run's own user_id stamp must match the
  acting owner's raw value (or the legacy "default" stamp) or the read
  404s. Established-ownership threads and every non-internal caller keep
  their existing thread-scoped semantics.
- Wire the gate into join, stream, messages, events and
  workspace-changes; reword the now-stale messages comment to track the
  new scoping semantics.

Regression tests: sub-resource reads 404 for a mismatched internal
owner while the matching owner reads them normally, and the owner-less
fallback branch (synthetic "default" filter on missing-meta threads) is
pinned. Red confirmed against the pre-gate head.

* fix(gateway): gate cancel and artifact archive for internal callers

Review follow-up on #5484 round 2: POST /cancel resolved runs unscoped
(require_existing=True only closes the missing-meta case — NULL-owner
meta rows still pass), so an internal caller acting for a different
owner could interrupt another owner's active run on a shared thread
while /join and /stream were already gated. The archive manifest and
download pair likewise leaked the other owner's delivered-file count
and a 200-vs-409 delivery oracle on NULL-owner threads (missing-meta
threads were already denied by require_existing=True).

All three routes now call _require_run_visible_to_scope; its docstring
records the extended coverage. NULL-owner-thread regression tests pin:
a mismatched internal owner gets 404 from cancel, manifest and archive
download, while the acting owner reaches the real conflict path (409 on
a terminal run) and reads the manifest (file_count 2).

* fix(gateway): tolerate state-less request stand-ins in the scope helpers

The new owner-isolation gate and _run_scope_user_id read request.state
directly, which crashed the FakeRequest-based unit suites for the run
events, workspace-changes and scope endpoints (backend-unit-tests shards
1/2/4 on #5484). Read the state object defensively first: a request
without state is simply not an internal caller, so those paths keep
their pre-gate semantics.

* fix(gateway): scope the thread token-usage aggregate by owner

Review follow-up on #5484 round 4: GET /{thread_id}/token-usage called
aggregate_tokens_by_thread(thread_id) with no user filter at all, so on
missing/NULL-owner threads an internal caller acting for owner A read
owner B's spend, model names, run count and (with include_active=true)
live activity; the NULL-owner variant reached browser sessions too.
build_context_usage's latest-model lookup was unfiltered as well.

aggregate_tokens_by_thread gains an optional user_id (mirroring
list_by_thread: explicit None = unfiltered, AUTO resolves the contextvar)
in the memory store, the SQL repository and the store base;
build_context_usage/_resolve_thread_model_name thread the scope through
the latest-run lookup; the token-usage endpoint passes
_run_scope_user_id's value. Established-ownership threads aggregate
unfiltered as before; shared/missing-meta threads narrow to the acting
identity. Stale helper-test comment reworded after the #5482 merge
adaptation.

* test(gateway): pin the unfiltered aggregate on established-ownership threads

Review follow-up on #5484 round 5: the established-ownership branch of
the token-usage scoping (store receives user_id=None) was the only
unpinned half of the contract — the round-4 call-assertions never set
app.state.thread_store, so their None came from the user-less stand-in
path. test_token_usage_unfiltered_on_established_ownership_for_
internal_callers seeds an established meta row plus runs stamped by two
different identities and asserts the totals fold (166 = 111 + 55);
together with the isolation tests it now catches both failure modes
(always-stamp narrowing and always-None leak).
